Application of least absolute shrinkage and selection operator logistic regression for the histopathological comparison of chondrodermatitis nodularis helicis and hyperplastic actinic keratosis.

J Cutan Pathol 2021 Jun 20;48(6):739-744. Epub 2020 Dec 20.

Department of Dermatology, University of Texas Medical School at Houston, Houston, Texas, USA.

Background: The distinction between chondrodermatitis nodularis helicis (CNH) and hyperplastic actinic keratosis (HAK) on the ear can pose a diagnostic challenge. We aimed to identify histopathological characteristics that could distinguish between CNH and HAK on routine sections using penalized least absolute shrinkage and selection operator (LASSO) logistic regression analysis.

Methods: Cases of CNH (n = 80) and HAK (n = 28) were analyzed for selected histopathological characteristics. Read More

We present a case of chondrodermatitis affecting the skin and cartilage of the nose, designated chondrodermatitis nodularis nasi. Clinically, chondrodermatitis presents as a singular, painful, ulcerated papule or nodule that results from prolonged pressure, trauma, sun exposure, or vascular compromise. Read More

Foreign Body (Solder) and Reaction to the Foreign Body Presenting As a Cutaneous Tender Tumor: Case Report and a New Acronym to Aid in Recalling the Differential Diagnosis of Painful Skin Lesions.

Cureus 2020 Feb 11;12(2):e6955. Epub 2020 Feb 11.

Dermatology/Dermatopathology, Compass Dermatopathology, San Diego, USA.

Cutaneous tender tumors manifest as painful dermal or subcutaneous masses. Acronyms, a memory aid created from the initial letters of other words, can be used to assist in recalling a list of conditions. We report the case of a man who presented with a painful lesion on his leg; 15 years earlier, hot solder had embedded beneath his skin at that location. Read More

Chondrodermatitis nodularis helicis in an adolescent boy: not just for old men.

Cutis 2019 Nov;104(5):E6-E8

Western Diagnostic Services Laboratories, San Luis Obispo, California, USA.

Chondrodermatitis nodularis helicis (CNH) is a solitary, chronic, painful, often ulcerated lesion on the upper portion of the ear, mostly in older men. We present an unusual case of CNH in a 17-year-old adolescent boy who was a lifeguard. Correlation between clinical and histopathologic characteristics of CNH is outlined in the context of the existing literature to increase awareness of this condition in younger patients as well as to guide appropriate management and surveillance.

Painful tumors of the skin: "CALM HOG FLED PEN AND GETS BACK".

Clin Cosmet Investig Dermatol 2019 13;12:123-132. Epub 2019 Feb 13.

Compass Dermatopathology, San Diego, CA, USA.

Painful tumors of the skin present as dermal or subcutaneous nodules. They can originate from several sources: adipose tissue, cartilage degeneration, deposition of bone or calcium, eccrine glands, fibrous tissue, infiltration of benign (endometrium) or malignant (metastatic neoplasm) tissue, muscle, nerve, or vascular structures. Although pathologic evaluation of the lesion is necessary to determine the diagnosis, it is possible to make a reasonable differential diagnosis based on knowledge of prior tumors that have appeared as tender lesions.

Pediatric chondrodermatitis nodularis helicis (CNH) in a child with Beckwith-Wiedemann syndrome (BWS).

Pediatr Dermatol 2019 May 17;36(3):388-390. Epub 2019 Feb 17.

Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania.

Chondrodermatitis nodularis helicis is an idiopathic degenerative process that presents as a painful nodule, papule, or ulcer on the helix or antihelix. It predominantly affects adults and is thought to be associated with trauma to the ear. We describe a case of pediatric chondrodermatitis nodularis helicis occurring in a child with a history of Beckwith-Wiedemann syndrome that was successfully treated with an excisional biopsy and relief from a recurrent source of pressure on the ear.

The Direct Use of Mobile Phone and the Occurrence of Chondrodermatitis Nodularis in the Antihelix: An Exemplificative Case.

Indian Dermatol Online J 2018 Nov-Dec;9(6):438-440

Department of Surgical Sciences, Audiology Unit, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan, Italy.

Chondrodermatitis nodularis helicis (CNH) is an idiopathic inflammatory painful condition of the ear characterized by a tender nodule located on the helix or antihelix. Even if various causes have been ascribed, such as a microvascular injury due to acute exposure to cold or trauma, pressure, or rubbing, etiopathogenesis still remains unknown. We describe the unusual case of a young female with a peculiar sequential onset of bilateral CNH in the antihelix region, possibly ascribed to the direct use of mobile phone without earphones.

Dermoscopy of chondrodermatitis nodularis helicis.

Arch Dermatol Res 2018 Sep 20;310(7):551-560. Epub 2018 Jun 20.

Department of Dermatology, Central University Hospital of Asturias, Avda. Roma s/n, 33011, Oviedo, Spain.

Chondrodermatitis nodularis helicis (CNH) is a benign auricular disease whose differentiation with nonpigmented tumors is mandatory. Clinical characteristics of CNH are well known, but there is no information about the dermoscopic features that could help differentiate CNH from squamous cell carcinoma and other non-melanoma skin cancers. To describe the dermoscopic appearance of CNH and to formulate a differential diagnostic model, we conducted  a retrospective, single center, observational dermoscopic study on a sample of 189 biopsy-proven lesions: 25 CNH; 26 squamous cell carcinomas; 62 basal cell carcinomas and 76 other benign and malignant tumors.

Review of the Etiopathogenesis and Management Options of Chondrodermatitis Nodularis Chronica Helicis.

Cureus 2018 Mar 26;10(3):e2367. Epub 2018 Mar 26.

Dermatology, State University of New York.

Chondrodermatits nodularis chronica helicis (CNCH), first described by Max Winkler in 1915, presents as a sore nodule on the helix or antihelix of the external ear. In this paper, we review the etiopathogenesis and management options of CNCH. This condition has a multifactorial etiology; however, sustained pressure from sleeping on one side is the favored theory. Read More

Texas A&M Health Science Center College of Medicine, Temple, Texas, USA.

Chondrodermatitis nodularis helicis (CNH) is characterized by a tender nodule located on the helix or antihelix. Age groups impacted by CNH vary from study to study, but the majority of studies report an average age range from 50 to 80 years. Various treatment options have been described in the literature, including surgical techniques, laser therapy, curettage, topical and intralesional corticosteroids, and pressure relieving techniques.

The Usefulness of 0.2% Topical Nitroglycerin for Chondrodermatitis Nodularis Helicis.

Actas Dermosifiliogr 2015 Sep 20;106(7):555-61. Epub 2015 May 20.

Background And Objective: Chondrodermatitis nodularis helicis (CNH) is a painful idiopathic degenerative condition involving the skin and cartilage of the helix or antihelix of the ear. Topical nitroglycerin 2% is a relatively recent treatment option for CNH that has produced good results, although with adverse effects (17% of cases). The use of a lower concentration would probably achieve similar results with fewer adverse effects. Read More

Chondrodermatitis nodularis chronica helicis in a patient with systemic sclerosis associated with primary biliary cirrhosis (Reynolds syndrome): A case report.

Eur J Rheumatol 2014 12 1;1(4):161-163. Epub 2014 Dec 1.

Department of Rheumatology, University Hospital Ramón y Cajal, Madrid, Spain.

Chondrodermatitis nodularis chronica helicis is a rare non-neoplastic inflammatory and degenerative process of the external ear, characterized by necrobiotic changes in the dermis that extend down to the perichondrium. This condition has been occasionally reported in patients with limited cutaneous systemic sclerosis but not in those with concomitant primary biliary cirrhosis; this association is known as Reynolds syndrome. We report a 70-year-old woman diagnosed with primary biliary cirrhosis at age 47 and with limited cutaneous systemic sclerosis at age 54 who developed a painful ulcerated nodule on the helical rim of the left ear shortly after the last diagnosis.
